Highly Sensitive Electrochemical Determination of Norepinephrine Using Poly Acrylic Acid‐Coated Nanoceria

We synthesized a poly acrylic acid‐coated nanoceria (PNC) and developed colorimetric and electrochemical methods for determining norepinephrine (NE) using 3,3′‐5,5′‐tetramethylbenzidine (TMB) as a redox marker. The PNC was the nanozyme, an oxidase mimic with effective catalytic activity. During the...
